Effect of Various Sealers on Healing of Teeth With Apical Periodontitis

Postgraduate Institute of Dental Sciences Rohtak99 enrolled

Overview

This study will compare the effect of three different sealers on healing of teeth with apical periodontitis after primary root canal treatment.

Various sealers with different chemical composition and properties are available but it is yet not clear if one sealer is superior to other in terms of healing of apical periodontitis. Three different groups of sealers will be used- a zinc oxide based sealer, an epoxy resin based sealer and a bioactive silicone based sealer. Mature mandibular permanent molar with the diagnosis of apical periodontitis (as confirmed clinically \& by periapical radiograph) will be chosen for the study. Primary non surgical root canal treatment will be performed. The sealer will be randomly selected just before obturation of root canals. The patient will be allotted to one of the three groups. * Group I: Zinc oxide eugenol sealer group. The material will be mixed according to manufacturer instructions and applied to canals using a lentulospiral and the obturation will be performed. * Group II: Epoxy resin based sealer group. The material will be mixed according to the manufacturer's instructions and obturation will be done. * Group III: Bioactive silicone based sealer: The material will be used according to the manufacturer's instruction and obturation will be performed

Inclusion Criteria: The inclusion criteria of the study will include: * Patient willing to participate in the study. * Age \>18 years. * No history of antibiotic use within the past month or requiring antibiotic premedication * No history of prior analgesic use during past 24 hrs. * Mature permanent mandibular molar having apical periodontitis requiring primary root canal treatment. * There must be a radiographic evidence of periapical radiolucency (minimum size 2mmx2mm) and a diagnosis of pulpal necrosis, as confirmed by negative response to cold and electrical tests; and absence of bleeding on entering the pulp chamber Exclusion Criteria: * Re-treatment * Unwillingness of patients * The presence of a difficult canal anatomy (root canals with an extreme curvature ≥30 deg), internal or external resorption and immature teeth. * Accident or complication during treatment (calcified canals ,inability to achieve apical patency in any canals) Immuno-compromised, diabetic, pregnant and hypertensive patients. * Teeth that are peridontally compromised

Outcomes

Primary Outcomes

Radiographic success

Change in apical bone density will be measured by Periapical Index (PAI) score. PAI score equal to or less than 2 will be categorized as success.

Time frame: 12 months

Clinical success

Absence of pain, sinus tract, swelling and mobility.

Time frame: 12 months
